Definitions

  • the present disclosure relates to sensors for measuring bioanalytes and to methods for making such sensors.
  • Electrochemical bio-sensors have been developed for detecting analyte concentrations in a given fluid sample.
  • United States Patent Nos. 5,264,105 ; 5,356,786 ; 5,262,035 ; 5,320,725 ; and 6,464,849 disclose wired enzyme sensors for detecting analytes, such as lactate or glucose. Wired enzyme sensors have been widely used in blood glucose monitoring systems adapted for home use by diabetics to allow blood glucose levels to be closely monitored. Other example types of blood glucose monitoring systems are disclosed by United States Patent Nos. 5,575,403 ; 6,379,317 ; and 6,893,545 .
  • WO 00/35340 A1 (Pipex Biomedical LLC) published 22 June 2000 discloses a sensor assembly including a catheter having a catheter sheath adapted for insertion in a patient and a catheter hub connected to the catheter sheath.
  • the present invention provides a sensor module as defined in the appended claims.
  • FIGS. 1-6 illustrate a sensor module 20 configured in accordance with the principles of the present disclosure.
  • the sensor module 20 includes a module body 22 having a distal end 24 positioned opposite from a proximal end 26.
  • the module body 22 is preferably constructed of a molded plastic material.
  • the module body 22 includes a first molded piece 22a secured to a second molded piece 22b at a part line (see FIG. 5 ).
  • the parts 22a, 22b are molded using a manufacturing process such as a continuous insert micro-molding process.
  • the module body 22 includes an analysis cell housing 28 positioned adjacent the distal end 24 and a skin piercing member anchor 30 positioned adjacent the proximal end 26.
  • a flexible linkage 32 ( FIG. 2 ) mechanically connects the analysis cell housing 28 to the skin piercing member anchor 30.
  • the flexible linkage 32 is configured to allow the analysis cell housing 28 and the skin piercing member anchor 30 to move relative to one another along an axis 31 that extends through the module body 22 from the proximal end 26 to the distal end 24.
  • the analysis cell housing 28 defines an analysis cell 50 ( FIGS. 3-6 ) at which a fluid sample (e.g., a blood sample) can be analyzed using a sensor structure, such as a wired enzyme sensor arrangement, in fluid communication with the analysis cell 50.
  • the sensor module 20 also includes a skin piercing member 34 (e.g., a cannula, a needle, a lancet, or other structure) aligned along the axis 31 (see FIGS. 3 and 4 ).
  • the skin piercing member 34 includes a base end 35 positioned opposite from a piercing tip 37.
  • the base end 35 of the skin piercing member 34 is secured to the skin piercing member anchor 30 and the skin piercing member 34 extends distally from the skin piercing member anchor 30 through a passage 36 defined by the analysis cell housing 28.
  • the passage 36 includes a distal end 38 positioned opposite from a proximal end 40.
  • the passage 36 includes a capillary slot 46 ( FIGS. 3 and 4 ) that provides fluid communication between the analysis cell 50 and the distal end 38 of the passage 36.
  • the distal end 24 of the module body 22 is placed against a patient's skin at a sampling location where it is desired to take a fluid (e.g., blood) sample.
  • a fluid e.g., blood
  • the skin piercing member anchor 30 can be driven distally along the axis 31 by an actuator (i.e., a driver) that couples to the skin piercing member anchor 30.
  • an actuator i.e., a driver
  • the skin piercing member anchor 30 slides within the passage 36 from a retracted position (see FIG. 3 ) to an extended position (see FIG.
  • the tip 37 of the skin piercing member 34 extends distally beyond the distal end 24 of the module body 22.
  • the distance the skin piercing member 34 extends beyond the distal end 24 of the module body 22 is preferably selected to ensure that a blood sample will be drawn efficiently.
  • the skin piercing member anchor 30 is then pulled back proximally by the actuator causing the tip 37 of the skin piercing member 34 to be retracted back into the passage 36.
  • an analyte level e.g., the blood glucose level
  • a controller such as a microcontroller, a mechanical controller, a software driven controller, a hardware driven controller, a firmware driven controller, etc.
  • the controller can include a microprocessor that interfaces with memory.
  • the controller would typically be integrated into an analyte monitor, such as a glucose monitor, having user interfaces for receiving user input (e.g., buttons and switches) and/or providing user output (e.g., a display for displaying the sensed analyte reading).
  • analyte monitor such as a glucose monitor
  • user interfaces for receiving user input (e.g., buttons and switches) and/or providing user output (e.g., a display for displaying the sensed analyte reading).
  • the flexible linkage 32 of the module body 22 preferably has a compressible configuration that enables the flexible linkage 32 to compress axially along axis 31 as the skin piercing member anchor 30 moves the skin piercing member 34 from the retracted position to the extended position.
  • one example flexible linkage 32 includes two linkage members 32a, 32b. Each linkage member 32a, 32b has a first end integrally formed with the skin piercing member anchor 30 and a second end integrally formed with the analysis cell housing 28.
  • Each of the linkage members 32a, 32b includes an intermediate flex or hinge point 70 (e.g., a central hinge point) that enables the linkage member 32a, 32b to flex radially outwardly relative to the axis 31 when the skin piercing member anchor 30 is moved in a distal direction relative to the analysis cell housing 28.
  • the flex or hinge point 70 also enables each linkage member 32a, 32b to flex radially inwardly toward the central axis 31 when the skin piercing member anchor 30 is moved in a proximal direction relative to the analysis cell housing 28.
  • the linkage members 32a, 32b expand radially outwardly from the axis 31 to provide axial shortening of the linkage members 32a, 32b along the axis 31, and contract radially toward the axis 31 to allow axial lengthening of the linkage members 32a, 32b along the axis 31.
  • the flexible linkage 32 also can be referred to as a "dynamic linkage" since it allows for relative movement between the skin piercing member anchor 30 and the analysis cell housing 28.
  • the passage 36 of the analysis cell housing 28 includes a tapered portion 36a, a sample transport portion 36b, and a skin piercing member guide portion 36c (see FIGS. 3 and 4 ).
  • the tapered portion 36a has a taper that narrows as the tapered portion 36a extends in a proximal direction through the analysis cell housing 28.
  • the tapered portion 36a of the passage 36 has a truncated, conical shape with a major diameter adjacent the skin engaging surface 74 and a minor diameter adjacent the capillary slot 46.

  10. Module de capteur (20) selon la revendication 1, dans lequel un connecteur de voie de médicament/substance chimique (256) permet la communication fluidique entre l'intérieur de l'élément de perçage (34) et une voie d'insuline (250) acheminée vers un réservoir d'insuline (252).
  11. Module de capteur (20) selon la revendication 1, dans lequel la cellule d'analyse (50) comporte un évent (90) qui permet à l'air présent dans la cellule d'analyse (50) d'être déplacé par un échantillon de sang.
  12. Module de capteur (20) selon la revendication 1, dans lequel la cellule d'analyse (50) est allongée dans une direction qui est généralement perpendiculaire à l'axe (31).
  13. Module de capteur (20) selon la revendication 1, dans lequel une partie de transport d'échantillon (36b) présente une section transversale plus importante qu'une partie de guidage de l'élément de perçage (36c).
  14. Module de capteur (20) selon la revendication 1, dans lequel une extrémité distale (72) du boîtier de cellule d'analyse (28) inclut une surface d'engagement de la peau circulaire (74).
